Multiple reports are coming out today to the effect that Arizona's (mainstream) business community is freaking out about this bill and near-certain boycotts if it becomes law. Everyone from Tim Cook at Apple (which was building a factory there) to the NFL Super Bowl Committee (next year's Super Bowl will be in Glendale) has come out against it.
Some of you are surely old enough to remember the shitstorm that ensued when Arizona refused to recognize MLK Day in the 1990s (among other things, the NFL yanked a Super Bowl because of it). The state legislature eventually came back with its tail between its legs and enacted the holiday.
Let's hope Brewer gets the message here.
